Flowplant Century Pump Manual FOREWORD This manual is primarily concerned with the Harben Century Type Pump. In addition, general safety and operating information for the equipment into which the pump is installed is also included. The conversion of pressurised water into a high velocity jet and its use as a cleaning and cutting tool is now familiar to, and used by, many people in a wide range of industries.
Flowplant Century Pump Manual HEALTH AND SAFETY AT WORK There are two main categories of risk. These are: a) Injury from impact of water b) Injury from environment. All persons involved in water jetting should be made aware of the risks.
